Answer:
Cam is at 6m below the surface of the water.
Step-by-step explanation:
Ignore all info except:
Ben is 8 meters below the surface of the water.
Cam is 2 meters above Ben
So now answer this;
What is Cam's position relative to the surface of the water?
This is too simple. Cam is 2 m above Ben which means two meter closer to the surface as Ben.
Ben was 8 m below the surface. By this Cam is 2 m closer to the surface, which is 8 - 2 = 6 m.
Cam is at 6m below the surface of the water.
Answer:
200 000 + 40 000 + 6 000 + 300 + 5
Answer:
a. x = 2 , x = -5
b. no real roots
Step-by-step explanation:
<u>a. x² + 3x – 10</u>
= x² - 2x + 5x - 10
= x (x²/x - 2x/x) + 5 (5x/5 - 2*5/5)
= (x - 2) (x + 5)
x - 2 = 0 x + 5 = 0
+ 2 +2 -5 -5
-------------- ---------------
x = 2 x = -5
x = 2 , x = -5
<u>b. 2x² - 4x + 3 </u>
This can't be solved because the equation has no real roots, and also the discriminant is negative.
